Five facts that I thought were interesting about Roman mosaics are that the design of how the tesserae will be laid out is scratched into a thin layer of mortar first, then the tesserae were placed on the mortar, following the pattern. Also, sometimes to make the mosaics very strong, they made a foundation out of broken stones and gravel, then put the mortar down and laid the tesserae out. Another fact I thought was interesting is that the way they designed mosaics is they had books called "pattern books" that had some designs to choose from. Sadly, none have survived. A fourth fact is that Roman mosaic artists almost never signed their work. Lastly, some of the first mosaics were made from colored rocks and pebbles instead of tesserae.
